WINDOW-VENTILATOR.

SPECIFICATION forming part of Letters Patent No. 287,055, dated October 23, 1883. Application filed May16.1883. No model.)

To end whom it may concern Be it known that I, JOHN GEORGE REINL, of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in \Vindow-Ventilators and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification, and in which- Figure 1 is a front elevation of the window of a railway-car fitted with my improved ventilator. Fig. 2 is a vertical sectional view of the same, showing the ventilator closed. Fig. 3 is a similar view, showing the ventilator open. Fig. 4 is a like view, showing the ventilator open to its greatest capacity for cleaning purposes; and Fig. 5 is a horizontal sec- 1 tional View through line 00 as in the preceding figures, looking downward.

Similar letters of reference indicate corresponding parts in all the figures.

My invention has relation to window-ventilators, which, while adapted for all general purposes, are more especially adapted for the windows of railway passenger-cars, and it consists in theconstruction and combination of two glazed sashes adapted to be operated simultaneously and in conjunction with each other, as and for the purpose hereinafter more fully described and claimed.

On the accompanying two sheets of drawin gs, 1? represents the frame or casing of a carwindow provided with my improved ventilator, which is located in the top part of the frame above the sliding window. This ventiand B,) the inner one of which, A, is pivoted at its lower end-upon spring-bolts I, so constructed and arranged that the sash may be removed by withdrawing the spring-bolts from the holes in the sash-frame with which they engage.

The outer sash, B, has pins or'studs K inserted into the end pieces of its frame, which project into grooved ways in the car-frame. The inner sash, A, is connected to the outer sash, B, by a jointed hinge consisting of the in Fig. 3 of the drawings.

lator consists of two glazed sashes, (shown at A two parts E and E, which are hinged together, as shown at e. Theinner arm, E, is provided with a spring-catch, F, the hook at the free end of which is adapted to engage a stop, f, fastened to the molding O on the inner side of the car-frame, as will appear more clearly by reference to Fig. 3 of the drawings. The outer end of part E of this connecting-hinge is pivoted on a pin or bolt, (1, in the top part of sash B, the lower end of which,when the ventilator is closed, impinges upon a weatherstrip, WV, so as to form a close and water-tight joint between sash B and the outside of the car-body.

Inserted between the two glazed sashes A and B is a removable wire screen, '0, for the purpose of preventing cinders and dust from entering the car when the ventilator is open. This screen may be fixed in position removably, by making the tongue I in the lower rail of its sash or frame adapted to be fitted into 7o a groove, L, in the joiner-work of the carframe, the upper rail, m, of the screen-frame being shaped so as to beslipped between dovetailed blocks M. Thus by'disengaging the top rail from the blocks W and lifting the screen-frame out of its groove L it may readily be removed.

The top rail of the inside sash, A, has a spring-catch, D, provided with an inwardlyprojecting knob or thumb-button for operating it and catching into a notch, D, in the top molding, O, of the frame. By pulling downward upon this knob, the upper end of sash A will be released, so that the sash may be swung open upon its pivot-bolts I, as shown It is prevented from opening too far by the spring-catch F striking with its upper hooked end against the stop-plate f. Sash A being connected by the jointed hingeE E' with outer sash, B, in the manner hereinbefore described, it follows that the outer sash will be swung open, as shown in Fig. 3, so that the air will enter from below on the outside, and then, passing through the screen 0, will enter the car over the top of 9 5 the inner sash, A, as indicated by the arrows.

If, however, it is desired to open both sashes wide for the purpose of cleaning them on the inside, this is accomplished bydepressing'the free ends of the spring-catch F, wliich disengages its hook from stop f, so that both sashes may be thrown into the position shown in Fig. 4, in which position they can readily be cleaned on the inside, or on the sides facing each other. If it is desired to remove the sashes entirely from the caraframe, this may be done by releasing the spring-bolts Ifrom sash A, disconnecting the jointed hinge between the two sashes, and slipping the guide-pins K of the outer sash out of the grooves or ways in which they slide.

The advantages of my improved ventilator will, from the foregoing description, taken in connection with the drawings, be readily understood without requiring extended explanation. It will be seen that both sashes are opened simultaneously and by a single operaof my invention.

Havingthus described my improvement, I claim and desire to secure by Letters Patent of the United States- .1- The, combination of the glazed sash A, having spring-catch D, and pivoted at its lower end upon bolts I, jointed hinge E E, and glazed sash B, hinged or pivoted at its upper end in arm E of the hinge, and provided with studs or guide-pins K, substantially as and for the purpose shown and set forth.

2. The combination. of the glazed sash A, having spring-catch D, and pivoted at its lower end upon bolts I, stop f, jointed hinge E E, having spring-catch F, and glazed sash B, hung or pivoted at its upper end to the outer arm of the hinge, and provided with studs or guide-pins K, substantially as and for the purpose shown and described.

3. The combination of the glazed sash A, having spring-catch D, spring-bolts I, jointed hinge E E, having spring-catch F, stop f, and glazed sash B, hung at its upper end in the outer arm of the hinge, and adapted to impinge with its free or lower end upon the weather-strip W, substantially as and for the purpose shown and set forth.

In testimony that I claim the foregoing as my own I have hereunto affixed my signature in presence of two witnesses.
